My invention relates to improvements in methods and means for feeding aplurality of long strips of printed forms into a typewriter, said stripsbeing superimposed on.

each other and interleaved with carbon sheets, whereby the filling in ofthe successive forms with typewritten matter, and the production of therequisite number of carbon copies may proceed practically continuously.

The invention is an improvement over the structure of my co-pendingapplication Serial No. 21,502, filed April 8, 1925, now Patent No.1,699,794, dated J anuaryv 22, 1929.

The general object of the present invention is to provide a method andmeans for effecting this result.

. Contributory objects are the following:

To provide means for folding over the first set of forms against thesecond set of forms, drawing the loops of paper thus formed around theplaten by rotating the same backward by hand, typing the forms in theusual manner, pulling them forwardly over the carbons which are held inplace against forward movement and cutting off the finished forms.

To provide means for clamping the paper against the platen as the latteris rotated reversely by hand whereby the loops are formed automaticallywhen the paper is pulled down past the feed rolls.

To provide a platen having a recess in which the loops are received.

To provide overhanging supporting rods to which the carbon sheets may bereadily attached.

To provide these improvements in the form of an attachment which mayreadily be applied to any standard typewriter by merely substituting aspecial platen for the one m use.

To provide a knife for ished forms.

Other objects and advantages will be a parent from a considerationof'the embod ments of the invention illustrated in the drawings, inwhich continuous typing is ac complished merely by turning the knobs onthe platen shaft to rotate the platen first in the reverse directionfrom that in which it rotates step by step during the typing opercuttingoff the finning the operation;

atiorr; then after typing the forms pulling out the paper and tearingof? the forms without 4 is a frontelevation bf the platen; Flg. 5 is anenlarged elevation of one of the duplex bars for supporting two of thecarbon sheets;

Fig. 6 is an elevation of a modified and preferred form of duplex barsupport;

Fig. 7 is an end View thereof; and

Fig. 8 is a small diagrammatic view illus trating the operation of thedevice.

Referring to the drawings, 1 represents an ordinary typewriter which maybe of any approved design, the one selected for illustration being wellknown. In addition to the usual parts it has a knife 2 in front of theplaten 3. This platen is mounted on the usual shaft 4 having bearings 5and the usual ratchet 6, the latter, however, being spaced from the endof the platen to provide a clearance between the two. A clamp bar 7 ispivotally supported on the platen having its ends 8 bent downwardly andthen inwardly to form pivotal supports 9, received in end openings insaid platen.

A plurality of metal frames or bars are provided for supporting sheetsof carbon paper. They may be made in various forms and operateddifferent ways. One of these carbon holders, see Fig. 5, consists of asmall rod 10 passing through an opening in the platen and havingdetachable ends 11 extending upwardly and then inwardly to form bars 12and 13 spaced from each other and supported by one end only, wherebythey overhang the platen. Each of these bars is adapted to support asheet of carbon paper,

as hereinafter explained. A second similar frame comprises the rod 14having bent ends 15 and overhanging bars' 16 and 17, each 'of the latteradapted to support a sheet of carbon paper.

The clamping frame and the two carbon frames are each provided with pins18, 19.and 20 (Figs. 2 and 3) which limit their movement in onedirection. They may be swung in the other direction, however, into therecess 21 in the platen as shown in Fig. 2.

In using the machine a plurality of long strips of printed forms arepulled forwardly, face downwardly, along the top of the platen.Horizontal bars 12, 13, 16 and 17 to each of which one end of a sheet ofcarbon paper is secured, are placed between said strips of printedforms. Theends of these supporting rods extend beyond the lateral edgesof the strips of paper and are then attached to the rod 10. In the formshown in the drawings, Fig. 3, provision is made for five such printedforms 22, said printed forms being stored at the rear, in the usualmanner. Provision is made in this instance for four sheets of carbonpaper 23, the rear end of each of which is looped around one-of the bars12, 13, 16 or 17, the carbon paper being pasted to itself to form anopen loop, whereby these loops may readily be slipped over said rods,half of them from one end and the other half from the other end thereof,as will be understood from an examination of Figs. 4 and 5. The sheetsof carbon paper are a little shorter than the height of the superimposedforms whereb the latter initially extend beyond the car ons as shown inFig. 3 to facilitate grasping the same by hand.

The preferred form of carbon support is shown in Figs. 6, 7 in which thetransverse rod 24 has its ends bent upwardly, one of them being bentoutwardly, and the other being bent inwardly as at 25 and 26, these bentportions constituting guides to receive the detachable rods 27 overwhich the carbon paper is slipped. Many platens are hollow thuspermitting the bar 24 with its upwardly bent ends to pass through thesame before the end plates are secured thereto. The-rods 27 are arrangedone in front of the other.

The printed forms are guided in their movement toward the platen by amember 28 secured to the carriage and havin its ends bent upwardly toform vertical gui es. Also the clamp bar 7 is struck upwardly as shownat 29, leaving a pair of shoulders which guide the paper over theplaten.

In using the typewriter, the operator turns the platen by hand in adirection the reverse of the usual operation, whereupon the clamp 7 andthe carbon supporting frames are moved toward the laten. In theparticular mechanism shown erein the said parts tend to swing to therear along the arc of a circle as the forward movement of the paper isobstructed more or less by the upper end of the two spring pressed feedroll supports 30, which carry the feed rolls 31 and the knife 2, andthus the paper is automatically clamped to the platen at a predetermineddistance from the end of said sheets, i. e. a distance approximatelyequal to the length of a printv ed form. Although the clamping membermoves inwardly along the arc of a circle, it is evident that it may becaused to move inwardly in any one of a number of different carbonsbetween the outer half of the sheets of said group. The inner halfmerely serve as a backing.

As the typewriter is operated in the usual way, beginning atthe top lineto be filled in, the platen is rotated in the usual direction,

-i. e., forwardly, and the forms are gradually fed out of the machineuntil the bottom line is reached in which position the clampin bar andassociated carbon holding bars wi have been rotated from the positionshown in Fig. 2 almost to the printing line, after which the operatorturns the platen by hand a little further in the same forward directionto feed the printed forms completely out of the machine. Thereupon theoperator seizes the forward ends of said forms, which as stated, projectperhaps half an inch beyond the forward end of the carbon sheets, aboutas shown in Fi s. 1 and 3, and by pulling said forms forwarglyflhecarbon sheets are left behind, being held in place by the transversebars to which they are attached, so that said printed forms slide overthe carbons leaving a second set of forms in proper typing position withreference to the carbons. The platen is then' rotated in the reversedirection, in the manner previously described, leaving the completedforms projecting from the top of the machine wlth no carbons betweenthem whereupon they are seized and torn off against the knife 2, whichis located just in front of the platen. T hetyping operation thenproceeds and the o erations are repeated. Such rotation is ma e possibleby virtue of the recess 21 into which the various cross bars swing, sothat said cross bars and the paper looped thereover do not protrudebeyond the surface of the platen to an objectionable extent. In otherwords, where a small number of carbon copies are to be made, one or two,it may be possible in some .to fall back in said recess independentlycases to use an ordinary platen without a recess cut therein, as theprojection caused by the loops of aper will ride under the feed rollers31 which spring back sutficiently for the purpose. Said cross bars arearranger;

0 each other, and are arranged to lie side by side rather than one overthe other so as to fitinto the available space very compactly.

The improvements may be applied to an 017- dinary typewriter merely bysupplying a special platen, which may be placed in the bearings fromwhich the regular platen has been removed to permit the use of myimproved platen. Additional feed rolls are unnecessary as the paperloops areclamped against the platen by the pivoted clamp, which holdsthem in place without additional feed rollers. It will be understoodthat the printed forms in practice are very long, enough to supplyseveral thousand individual'printed forms and are conveniently stored tothe rear of the typewriter, whereby after said forms are once threadedthrough the machine with the carbon sheets between them, it isunnecessary to interrupt the typing operation, and thework may proceedas a continuous operation.

Another type of printed form which may be used is one having itsalternate lateral edges joined, in a well known manner.

Although as shown in Fig. 2, the length of each printed form is lessthan the circumference of the platen, it is possible to use printedforms having a greater length, necessitating rotation of the platen morethan a complete turn, particularly when the vertical height of thetyping area is no greater than the circumference of the platen.

As will be seen in Fig. 2, the arrangement of the clamping bar and thecarbon holding bars is such that said bars fold. into the recess in theplaten in such a way that the paper does not project too far beyond thenormal circumference of said platen. The carbon holding bars shown inthis figure are arranged in pairs one over the other. In the referredarrangement shown in Figs. 6 and the carbon holding bars are not onlyarranged one over the other, but they are displaced circumferentially,that is, one is arranged in advance of the other, the rear one being thehigher of the two and the end view of the support for the bars being Vsha ed as shown in Fig. 7. When this V shape frame is folded rearwardly,the two bars lie nearer the surface of the groove in the platen. Inother words, a smoother arrangement is presented when all the bars areswungback into the groove.

Instead of having a series of individual bars with endportions'extending at right angles thereto, a single structure may beprovided at each end of the platen carrying not only the clamping barbut all of the carbon holding bars so that said bars maintain -a fixedrelation as they swing up or down.

Although the devices shown are particularly useful in making a largenumber of carbon copies of typewritten matter, it is evident that theprinciple of operation is applicable to a single sheet of paper and asingle carbon sheet, in which case only the clamp bar is necessary, thecarbon sheet being secured to the clamp bar and thus arranged to makethe necessary carbon impression when the single sheet of paper is foldedback on itself. The carbon copy is thus made immediately to the rear ofthe area on which the original impression is made and on the oppositeside of the paper, in which case the strip of paper is drawn'forwardlyfar enoughto withdraw both the original and the carbon, in other words,twice as far as in the cases previously described.

By using the attachment described, it is also possible to obtain atabulation of the totals of the individual printed forms, where such isdesired, merely by securing an additional narrow sheet of carbon paperto the clamping bar and passing an additional strip of paper under saidclamping bar and over the upper printed form. After each operation thisstrip of paper, which may be a wide sheet or merely a narrow strip atthe right hand side of the machine, is pulled forward a short distance,for example a half inch or less, enough to receive the successive totalsthereupon, which appear in the reverse order, i. e. the totals read fromthe bottom up. If it is preferred to print the totals in consecutiveorder from the top down, an additional carbon holding bar may be mountedon the platen to support a sheet of carbon paper between the top printedform and the tabulating sheet which passes under the clamping The termstop, bottom, front, rear, horizontal, and similar terms used herein asdescriptive of the particular embodiment of the invention shown are tobe understood as used for convenience in a relative sense and not in alimiting sense.
